This isn't at all true. If it were racials that caused the differences in factions, then Europe would see the same problem, but the EU sees the opposite (way more Alliance than Horde). Also, there wouldn't be so much complaining about EMFH.

I'm not saying there is no difference in racials, because there is, but it's not nearly as tangible as people would like to believe.

some of the results might be favoured a bit to more alliance side as i did do some random bgs with 2-4 friends and that usually nets a 70-90% win rate

so winning abt 42% of random bgs taking out 40m
and winning about 49% with all bgs taking into account

my results would be a lot worse if i didnt q up with friends, i would guess 35-40% win rate with those 2 40m bgs taken into acct
would be more accurate as if i q outside of the 2 40m, i rarely get the 40m bgs anyway cos of the blacklisting by horde

so i still think if you're are q'ing alone as alliance it break down to instant q for 35-40% chance to win VS ~10-20min q time for 60-65% chance to win for horde
